Fuel Economy in Cold Weather

Fuel economy tests show that, in short-trip city driving, a conventional gasoline car’s gas mileage is about 12% lower at 20°F than it would be at 77°F. It can drop as much as 22% for very short trips (3 to 4 miles).

The effect on hybrids is worse. Their fuel economy can drop about 31% to 34% under these conditions.

Why is winter fuel economy lower?

Cold weather affects your vehicle in more ways than you might expect:

Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids.

It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures.

They had fast and friendly service. I called one day and they fit me in the next day. Was able to pick my car up just after lunch (oil change and block heater plug replacement). Reasonable prices for an independent shop! They even e-mailed me a report based on their complimentary inspection during the oil change to identify any concerns with other parts of the car. If you live nearby I would definitely recommend bringing your car here!read more

My car threw a code out of the blue, as vehicles tend to do. I called them in the morning they got my car Diagnostics done and called me in less than 2 hours! They had my car back to me less than 3 hours after that! They were polite, honest, and cooperative. I would definitely take my car back to them!read more

We generally drive older vehicles have been using Lai's services for over 30 years. We have never had a complaint. They always give you a good estimate of what a repair will cost and are helpful to prioritize what should be done right away and what can wait. Fast and friendly service.read more

I've taken my Jeep to Lai's for service regularly for about 10 years. Chris and his team are always super professional, very efficient, and are very reasonably priced compared to the competition. They are on a first name basis with many of their clients. I generally receive same day service, or for sure within the week. Parking is easy too on their property. I often recommend them to my friends and family.read more

Took in my son’s car. They gave us accurate information and allowed us to make a decision. You can’t ask for more than that. I had researched what I needed done but other places always gave me information that suited them. These guys just let you know your options and you decide.read more

Chris and his team did quick and superb work on my truck. They listened to my problem and fixed the issue. I asked for new brakes and check for the squealing in my wheels. They fixed the squealing, and showed me in detail why I didn't need new brakes. Not only did he fix the issue fast, he saved me money by not ripping me off replacing pads that didn't need to be changed. Honest and reliable. Thank you.read more

Chris got my car in for tire swap the same week, and diagnosed an annyoing tire sensor problem (batteries) that my previous shop said was likely due to failing computer module LOL. Lai's provides efficient service and honest diagnostics. Will definitely take my car back there!read more
